NCTM Illuminations: Pi Filling, Archimedes Style: In this unit, students inscribe and circumscribe regular polygons in and around the unit circle, which is known to have an area of π. Students then consider the area of the polygons, using either an applet or a graphing calculator. The area of the n-gons approaches π as n increases. Similarly, students consider the perimeter of inscribed and circumscribed regular polygons in and around a circle with unit diameter. This exploration also leads to an approximation of π.  Also see NCTM's Computing Pi applet.
